Inhibition of return (IOR) is a response delay that occurs when the target is preceded by an irrelevant stimulus (cue) at the same location. IOR can be object based, as well as location based. The aim of the present study was to investigate the role of the pragmatic features of a visually presented object in causing IOR. Two experiments were carried out using different objects as stimuli, for which the graspable part (affordance) was clearly defined. The presentation of a whole object, with the part commonly used to grasp it located below, served as a cue. The presentation of either the graspable or the ungraspable part of the cued or uncued object served as the target. Results showed that responses were slower when the graspable part was shown in the cued location than when the ungraspable part was shown in the same location. The effect was apparently linked to the kind of action necessary to grasp an object.
返回抑制（IOR）是指当目标之前在同一位置出现无关刺激（线索）时发生的反应延迟。IOR既可以基于物体，也可以基于位置。本研究的目的是调查视觉呈现物体的实用特征在引发IOR中的作用。使用不同物体作为刺激进行了两项实验，这些物体的可抓握部分（可供性）被明确界定。呈现一个完整物体，其通常用于抓握的部分位于下方，作为线索。线索物体或非线索物体的可抓握部分或不可抓握部分的呈现作为目标。结果表明，当可抓握部分出现在线索位置时的反应比不可抓握部分出现在同一位置时的反应更慢。这种效应显然与抓握物体所需的动作类型有关。
